Installation and
Placement
WatchDog loggers have the versatility to be located in any
micro-climate for recording weather data. The sensors and
the mini-radiation shield include hardware for attaching them
on a 1” to 1¼” outside diameter mast (pipe). Use a 5’ - 10’
length of conduit or pipe as the mast mount. When
purchasing and/or cutting the mast to size, plan on placing
1½’ - 2’ of the mast into the ground.
For outdoor and greenhouse use, the logger should be
placed in a 3663A Radiation Shield to protect it from solar
radiation and other sources of reflected heat. The radiation
shield also protects the A125 and A130 loggers from rain. To
place the WatchDog into the radiation shield, unscrew the
two finger-nuts and remove the top of the radiation shield.
Important:
External sensor wires
connect to the logger from the side
at the point where the top and bot-
tom sections meet. Secure the
external sensor wires to the mast
just below the radiation shield with
a plastic tie to ensure that the
sensor wires do not become
disconnected while recording.
